Description
Technical field
The present invention relates to a kind of hollow spindle, belong to twisting apparatus hollow core spindle technical field with spiral-guide groove.
Background technology
Air-jet eddy-current spinning collection rove, spun yarn, winder coiling one, shortcoming such as it is bigger to have overcome in traditional twisting process parts revolution inertia, and twisting efficiency is lower utilizes the high speed swirling eddy to twist free tail end fiber resultant yarn, and spinning speed is up to 450m/min; The yarn that makes has dual structure, is made up of core fibre and outer looping fiber, has the outward appearance of ring spinning, but outer looping spiral fiber is tight not as machinery control looping, and yarn strength is powerful high not as ring spinning line.
Improve the powerful way of air-jet eddy-current spinning yarn except that being optimized to the yarn process parameter, also can be through hollow spindle morphosis in the twisting chamber is designed, make wrapper fibre self have wrapped yarn body after certain twist, thereby improve yarn strength.
Chinese invention patent CN 101476180 B; The denomination of invention self-twisting hollow ingot special for jet air vortex spinning; As shown in Figure 1; Hollow spindle 1a comprises fiber entry 11a and hollow spindle passage 12a, it is characterized in that having Surface Groove 13a on fiber entry 11a and the hollow spindle passage 12a, and the inner surface of Surface Groove 13a is linear or camber line shape.Inlet surface groove 13a helps to increase the frictional force of free tail end fiber and hollow spindle 1a inlet, thereby makes fiber when hollow spindle 1a rotates, self producing certain rotation, finally causes yarn texture tight, and yarn strength is increased; But should invent the action rule of considering twisting chamber swirling eddy and hollow spindle outer surface; Do not consider that the free tail end lodging of fiber is in the actual conditions of hollow spindle inlet outer surface in the twisting chamber yet; Fiber produces the DeGrain that self rotates when hollow spindle 1a rotates; Yarn texture is loose, and brute force is not high, the resultant yarn evenness fault.
Summary of the invention
The purpose of this invention is to provide a kind of have spiral-guide groove, resultant yarn consolidation, high, the dried uniform hollow spindle of bar of intensity.
The technical scheme that realization the object of the invention is taked is following:
A kind of hollow spindle with spiral-guide groove; Be divided into the upper, middle and lower, top offers fiber entry and yarn-guiding duct, and the bottom is " protruding " font structure; Described fiber entry is the slick and sly structure of chamfering; Outer surface at top and middle part evenly is provided with guide channel, and guide channel extends to the bottom at middle part from the fiber entry on top, and guide channel is a spirality.
